Carbon combines with some metals to make carbides such as tungsten carbide. This makes it desirable as tips for cutting tools such as drill bits.
An oversight in a radioisotope dating technique used to date everything from meteorites to geologic samples means that scientists have likely overestimated the age of many samples, according to new research from North Carolina State University.

“Some mathematical and geophysical considerations in radioisotope dating applications” : 10.13182/NT16-98 Abstract: Some quality considerations for use in isotopic dating are presented to identify and correct heretofore unidentified overestimate scenarios.
Just one gram of activated carbon has a surface area in excess of 500 m (determined by nitrogen gas adsorption).
Activated carbon is usually derived from charcoal but also from carbonaceous source materials like nutshells, peat, wood, coir, lignite, coal and petroleum pitch.“So, there’s not a simple equation that can be applied to every circumstance.
